Title: Corrugated rubber hose
Inventor: SMITH ALFRED JOHN
IPC: B29D23/18
Filed: 1954-04-13
Abstract: A reinforcing cord of cotton is helically would around a rubber tube on a perforated mandrel and differential air pressure is applied to the tube to cause those parts of the tube not restrained by the cord to form helical swellings.  The tube is then axially collapsed to provide corrugations of the desired pitch and vulcanized.  A stockinette cover may be drawn over the tube before the step of preforming the corrugations. Circumferential corrugations are formed in a similar manner. Alternatively, an inflating box as described in Specification 647,084 is used to preform the corrugations, and in this case the reinforcing cord can be applied to the tube after removal thereof from the box.  According to the Provisional specification the cord may be of rayon, nylon or other natural or synthetic fibre and be applied in the form of multi-start helical windings.

Title: Automatic choke valve apparatus for an internal combustion engine
IPC: F02M1/10
Filed: 1975-03-14
Abstract: 1494680 Automatic choke system HONDA GIKEN KOGYO KK 14 March 1975 [15 March 1974] 10875/75 Heading F1H The action of a choke valve in an I.C. engine is controlled by a control circuit via a reversible pulse motor in response to command signals representing: - closure of the ignition switch, activation of the engine starter, initial firing of the engine, and predetermined duration of continuous firing of the engine. The choke assembly, Fig. 1, comprises a choke valve 2 driven open via linkage 10, 13, 14 by a pulse motor 5, through the interengaging lugs 8, 9 and driven shut through the coil spring 7. The latter allows the valve 2 to close and the pulse motor to wind up the spring to increase the force holding the valve shut. This will continue to the point where the pulse motor stalls. The control circuitry Figs. 3 and 4 (not shown) comprise a series of switching relays connecting capacitance and resistance &c. to the pulse motor to drive it at the required speed in the required direction and a logic circuit which interprets the command signals and energizes the appropriate relays. In operation the action of the choke is as follows:- Fig. 5 - on closure of the ignition switch, the pulse motor drives the shaft 6 in the closing direction at a speed corresponding to the line AB through a choke closed position to a pulse motor stalled region BC. At C activation of the starter, causes the shaft to be driven for a predetermined time in the opening direction at a speed controlled by engine temperature corresponding to the line C, D. After said predetermined time the motor is stopped until at E the engine fires. The shaft then drives at a speed for a predetermined time corresponding to the point F. If the engine is still firing when the position F is reached the shaft drives the choke valve to full open corresponding to the line FG at a rate governed by engine temperature. The portions CD and FG differ in gradient since the pulse motor is set for a higher basic speed during the CD phase. The choke arrangement may be used in a carburetter for an engine having main and subsidiary combustion chambers, Fig. 7 where a second choke valve 2a is driven through a lost motion linkage 45. The arrangement is such that other than at fully open or closed choke valve 2a will be open more than choke valve 2, Fig. 9 (not shown).

Title: Automatic valve system for filling and emptying liquid tanks
IPC: B64D39/00
Filed: 1949-04-25
Abstract: 668,094. Valves. MULLER, J. April 25, 1949 [May 12, 1948], No. 10945/49. Class 135. An automatically operating valve system for filling and emptying liquid tanks, e.g. in aircraft, comprises a valve box in the tank provided with a filling or emptying nozzle for connection with a pipe, and a float box also in the tank, the valve box containing a first spring-loaded valve for closing the nozzle at the inside of the valve box, and a second spring- loaded valve connected to a primary float by a toggle joint which is broken when the float reaches a predetermined level and allows the spring to close the second valve on an internal lateral aperture of the valve box. A liquid supply hose is coupled to the nozzle 6 so that the pressure opens the spring- loaded valve 14 and flows through a valve box 1 secured to the bottom or side of a tank 4 and through an aperture 9 into the tank. As the tank fills, a float 66, rises and, through an adjustable rod 3 and lever 40, breaks a toggle joint 36, 37 and by means of a bell crank 33 and spring 25 moves a valve 12 out of a bell 22, so that the liquid flow closes the valve on a seat surrounding the aperture 9, a dashpot 20 retarding this action. The float is enclosed in a ported box 2 secured to the top or side of the tank, the box being provided with a relief valve 57 which allows liquid or air to escape via pipe 54 if the valve system does not operate. An aperture 59 in the relief valve ventilates the tank under reduced pressure and when the tank is filled the aperture is controlled by a valve 64 carried by a bell-shaped float 62 moving between the valve 57 and stops 65 on a guide 61 carried by this valve. If the tank is inverted, the valve 64 closes the aperture 59. To empty the tank a hose coupled to the nozzle 6 has a part opening the valve 14 so that hydrostatic pressure opens the valve 12 slightly and as the liquid level falls the float 66 allows the valve to re-enter the bell 22. A cap is secured to the nozzle by studs entering a groove and carries a valve which is forced on to the nozzle by a screwed handle.

Abstract: 1506181 Sweep tuning and channel switching arrangements MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 March 1975 [22 March 1974 (2) 9 July 1974 (7)] 11332/75 Headings H3Q and H3A In a search tuner having a voltage controlled oscillator VCO 11, Fig. 2, whose frequency is varied by a sweep voltage obtained from an integrator 15, the output of the VCO is connected to a frequency discriminator 9 the output of which is fed via a LPF 13 to an arithmetic unit 17 for summing or differencing the output from the LPF with a sweep driving voltage 16 to provide an output via the integrator to vary the oscillation frequency of the oscillator, the sweep of the oscillator is halted when the output voltage from the LPF becomes a steady D.C. and the oscillator is arranged to be maintained at the halted frequency. The low pass filter 13 can be passive (Figs. 4a and 4b, not shown) or active (Fig. 4c, not shown) and the adder 17 can be an operational amplifier (Fig. 3, not shown) or a subtractor (17') can be used instead of the adder. The clamping circuit 14 can be a diode (54, Fig. 10, not shown) or an operational amplifier (57, Figs. 11 and 12, not shown) having a diode (56) in a feedback path thereof. In a channel selector Figs. 6A, 6B, frequency discriminators 25, 26 each corresponding to 10, 12 and 13 of Fig. 2 control sweep oscillators 20 and 23 via voltage sweep circuits 31, 32 which correspond to 15 and 17 of Fig. 2 so that they alternately sweep at frequency differences of #f 2  and #f 1  (Fig. 7, not shown). Switching circuits 33, 34 are also controlled for opening or closing frequency locking loops 20, 22, 24, 25, 33 and 31; 23, 22, 24, 26, 34 and 32. The required channel is selected by keyboard 38 and when the count in counter 37 corresponds to the required number of alternate sweeps of the oscillators to tune the receivers 18, 19, 21 to the selected channel the output from a comparator 29 opens a gate 28 to stop the alternate sweeping operation. A programmable counter 45 enables the counter to count from the lowest number in one of a number of blocks corresponding to the lower VHF, higher VHF or UHF band in which the channel selected occurs so that the counter can effectively skip counting the channels corresponding to a lower band. A multiplexer 49 switches the power source for the UHF or VHF band and tuning coils for the low or high VHF band. In a modification (Figs. 8A, 8B, not shown) the mixer 19 also functions as the auxiliary mixer 22. In a further modification (Figs. 9A, 9B, not shown) the frequency discriminators 25 and 26 are replaced by a mixer (51) fed with an oscillator signal (50) and the sum and difference frequency representing #f 2  and #f 1  are detected by a discriminator (53) the output of which controls the monostable 27 as before.
